However, David mentions a director named Emile, though it’s been reported that Justin and Cody’s video is being directed by the legendary Wayne Isham, who has worked with the likes of The Rolling Stones, Michael Jackson, and Britney Spears.

Justin and Cody, who share Scooter Braun as a manager, are collaborating on a duets album that is set to drop in November. And they are gearing up for the imminent release of their first single.

‘It is a smack bang duets (album),’ Cody told The Daily Telegraph. ‘Justin has been a good mate of mine for a while. Its just us writing.

‘He told me he felt like I’d figured myself out and have grown into what he knows I will be so he was like, “I see you as that guitarist, singer songwriter you’ve always wanted to be”. I play all the guitars on the album.'

The Australian pop star then commented on his colleague’s bad boy reputation.

‘I can’t speak for him,’ he said. ‘I don’t get involved in any kind of drama, we are definitely different people and come from different places and different worlds but as far as to me, he has always been extremely cool and generous.’

Justin and Cody enjoyed dinner with their crew in a private area of Nobu on Friday night. Also present was Justin’s on-again girlfriend Selena Gomez.
